TUPELO, Miss. (AP) — A Mississippi man whose home and business were searched as part of an investigation into poisoned letters sent to the president and others has been arrested in the case, according to the FBI.

Everett Dutschke, 41, was arrested about 12:50 a.m. today at his Tupelo home in connection with the letters, FBI spokeswoman Deborah Madden said. The letters, which allegedly containedricin, were sent last week to President Barack Obama, Sen. Roger Wicker of Mississippi and earlier to an 80-year-old Mississippi judge, Sadie Holland.

Madden said Dutschke was arrested without incident. She said additional questions should be directed to the U.S. attorney's office. The office in Oxford did not immediately respond to messages Saturday.
